Abstract (en)

[origin: EP0292319A2] In a gear synchronizer, a clutch sleeve (12) has internal splines in continual engagement with external splines of a hub member (11) fixed to a shaft (21) and is axially shiftable to be engaged at its internal splines with external splines of a spline piece (24) mounted on a hub portion of a gear member (22) rotatable on the shaft. The gear synchronizer includes a support ring (14) encircling a conical portion integral with the spline piece and having external splines (14a) engageable with the internal splines of the clutch sleeve, a synchronizer ring (15) coupled with the support ring and having an internal conical surface (15a) for frictional engagement with the conical portion (24a) of the spline piece, an operation ring (16) coupled with the support and synchronizer rings in such a manner as to be axially displaced in response to relative rotation thereof to the synchronizer ring, a connecting ring (25) rotatably mounted on one side of the hub member and connected to the synchronizer ring, the connecting ring having an external conical surface (25a) for frictional engagement with an internal conical surface (16a) of the operation ring, and an annular waved spring (17b) disposed between the support and operation rings.
